Or you can use one of the widgets below to purchase the game directly. When buying a 4-packs, please remember that if you already own the game, you will either only receive 3 copies (Humble), or you won’t be able to purchase a 4-pack through Steam because you already have a copy. So what you need to do is purchase a 4-pack as a gift to someone else so they can distribute it. This applies to both Steam and Humble.
